【摘要】 地震采集施工因素与接收的随机噪音强弱密切相关。多次试验分析表明,环境噪音强弱主要与接收条件有关,尤其是检波器与地表耦合程度、检波器个数、组内距等因素关系密切,次生噪音强弱不仅与接收条件有关,还受激发条件的影响,调整激发因素增强有效波下传能量时,次生随机噪音能量也相应加强。更多还原

【Abstract】 Acquisition factors and seismic noises are closely related.Many experiments show that noises from environment are related to receiving conditions such as coupling between geophone and surface,numbers of geophone,element spacing and so on.Infrasound noises are not only related to the receiving conditions,but also the shooting parameters.If we enhance the penetrating energy,the infrasound noises will rise,too.更多还原
